This is a photo of the bottom of a hen that is having difficulty. Last week she started bleeding from her bottom we thought it was a prolapsed vent. We cleaned her up and isolated her in a dog crate, after a few hours she discharged egg yolk so then we figured an egg broke internally. We looked up info on this site and cleaned her again and rinsed her internally with warm water and vinegar, after several days she seemed back to her self, was eating and drinking ok no more sign of discharge, today she started bleeding again, I removed her and cleaned her again, when I was cleaning her I noticed she had something gunky coming out of her vent so I rinsed her out again, she had some blood and residue, maybe poop that came out but I also noticed she had some crusty, scaling stuff below her vent, this was new, I wiped her down it didn't come off, I put her back in the crate, now it appears she is still discharging some whitish stuff.
Any help would be appreciated, any ideas what might be wrong with her?
Thanks
